How to monitor MD 5 Checksum for WMI Win32_FileSpecification ?

With IPHost Network Monitor you can run WMI MD 5 Checksum monitoring of various devices in your network.

To create a WMI monitor for MD 5 Checksum, provide host name (it must be a Windows host) and specify custom WQL query:

SELECT MD5Checksum FROM Win32_FileSpecification

The MD5 algorithm is a well-known algorithm for computing a 128-bit checksum for any file or object. The likelihood of two different files producing the same MD5 checksum is very small (about 1 in 2^64), and as such, the MD5 checksum of a file can be used to construct a reliable content identifier that is very likely to uniquely identify the file. The reverse is also true. If two files have the same MD5 checksum, it is very likely that the files are identical. For purposes of MOF specification of the MD5 property, the MD5 algorithm always generates a 32 character string. For example: The string abcdefghijklmnopqrstuvwxyz generates the string c3fcd3d76192e4007dfb496cca67e13b. See http://www. rsa.com/pub/rfc1321.txt for details on the implementation of the MD5 algorithm.

Each instance of this class represents a source file with it's various attributes, ordered by a unique, non-localized identifier. For uncompressed files, the File property is ignored, and the FileName column is used for both the source and destination file name. You must set the 'Uncompressed' bit of the Attributes column for any file that is not compressed in a cabinet.
